IIRC, Zeus' thin-wall remover pre-dates Phil's and also fits Atom and Regina splined bodies.



Zeus was actually quite clever with their freewheel: not only does it accommodate that nice, thin-wall splined remover, but it also has slots that will work with the then-ubiquitous Regina two-prong remover. So if your mechanic wasn't quite up to speed with a new-fangled splined remover, you could still remove the freewheel with the traditional two-prong tool.
